1.) Group like terms: 4x+3x-5x+5x+5x-3x+2x-8x+2x-5x-5+7
2.) Add similar elements: = 4x+3x-5x+5x+5x-3x+2x-8x+2x-5x=0
3.) =-5+7
4.) Add/Subtract the numbers: -5 + 7 = 2
<u>Your Answer: 2</u>
Answer: f(x)= 2x -3
Step-by-step explanation:
Using the given information we can come up with two points that will be use to find the slope and y-intercept.
If you input 0 you get -3 so the point will be (0,-3)
If you input 7 you get 11 so the point will be (7,11)
Now use the points to find the difference in their y coordinates and divide it by the difference in their x coordinates to find the slope.
y coordinates: -3 - 11 = -14
x coordinates: 0 - 7 = -7
-14/-7 = 2
Since the slope is two, we will use the slope intercept formula (y = mx +b) to find the b which is the y intercept.
Use one of the points and input its x and y coordinates into the formula including the slope to solve for b.
-3= 2(0) +b
-3 = 0 + b
b = -3
f(x) is the same as y in the formula, meaning that the equation will be
f(x) = 2x -3
Answer:
600
Step-by-step explanation:
You would do 36,000 divided by 60 because there are 60 minutes in an hour, and it would be 600.
B) {x|x ∈ U and 2x is prime}
x is greater than 1.
the only even prime number is 2
2 times anything is even.
the minimum x value is 2. 2x is 4, therefore higher than the only even number
every value 2x will have a multiple of 2 so it will not be prime.
